Painting with concerning mark inside mount (9)
I believe the answer is:
rembrandt
'painting' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'concerning mark inside mount' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'mark' becomes 'brand' (synonyms).
'inside' indicates putting letters inside.
'mount' becomes 'mt'.
'brand' placed into 'mt' is 'mbrandt'.
're'+'mbrandt'='REMBRANDT'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for rembrandt that I've seen before include "Dutch painter, d. 1669" , "Influential Dutch artist" , "old master" , "One notably exhibited" , "Dutch painter, 1606-69" .)
